I was able to get past this error and to the server select screen by using the d3dx9_30.dll file posted on the wine site.
the direct download is here:

I did not need to use this file to get titanium to work. And I have not gotten past the login yet because I need to tweak my eqclient.ini file a bit. For some reason when I alt+ enter out of full screen, i enter windowed mode but the window stays black, and I can't alt+tab back. Plus I still have the full screen mouse issue, so I really cant click on anything to progress further. You can only tab so far.
